SPEGZFICATION forming part of Letters Patent No. 408,235, dated August6, 1889. Application filed April 27, 1887. Serial No. 236,299. (Nomodel.)

clear, and exact description of the invention,

that will enable others skilled in the art to which it appertains tomake and use the same,

reference being had to the accompanying drawings, forming a part of thisspecification, in which Figure 1 is a View of a drying deviceconstructed in accordance with my invention, in vertical section throughthe line y y of Fig. 1; Fig. 2, a top view; Fig. 3, an end View of thesame, and Fig. 4 a detail in perspective of a wing 0.

My invention has reference to devices for drying gray, bleached, sized,or colored warps or gains, or goods of cotton, silk, or wool, colored,bleached, or printed in the piece in cotton, woolen, or silk mills, orprint works immediately after they are colored, bleached, sized, orprintedin short, any material that can be dried by the application ofhot air. Many devices have been employed for the purpose of drying suchgoods or material, some of which are objectionable because the yarns orother material are exposed to contact with heated metallic surfaces,which in jure the surface or texture of the goods, and others becausethe process of drying is slow and imperfect by reason of theaccumulation of vapors in the chambers or pipes 011 which the drying isconducted, so that the heated air employed is more or less laden withmoistme.

It is the purpose of my invention to provide a means of drying thematerial by subjecting it to a series of blasts of dry heated air, andwithout bringing the material injuriously into contact with any heatedmetallic surface.

My device, as illustrated in the drawings, may be described as follows:a a is a pipe or chamber, of tin or similar material, preferably ofrectangular shape, as shown in the drawings, closed at one end and atthe other constructed so as to permit connection with a tube or pipefrom a hot-air blast. The broader side of this pipe or chamber a, whichit will be found desirable to construct as a plane surface, is providedwith narrow transverse openings Z) Z), extending from side to side anddisposed at regular intervals from one end to the other of the pipe.lVithin the chamber a a are placed the wings or curved pieces 0 c 0.These wings or curved pieces are con nected at their upper ends to theface of the pipe a a, containing the openings b b, so as to form anairtight connection and'extend from side to side of the box. They areplaced, respectively, at the rear of each opening b that is, at the edgeof the opening I) nearer the closed end of the pipe-and curve down- Wardand toward the open end, each of the wings, as they approach the closedend, being slightly longer than the preceding, the last wing touchingthe bottom of the chamber or pipe a a.

In operation the open end of the pipe is connected with an air-blast bywhich the chamber or pipe may be supplied with a continuous blast ofheated air. The warps, yarns, or piece goods (represented by d in thedrawings) are carried along over the openings Z) Z), either by hand orby suitable mechanical means. The heated air as it passes into andthrough the pipe to a is caught by the successive wings c c and forcedthrough the successive openings 1) 1) against the warps or othermaterial, by which it is dried, the moisture produced by the processpassing off into the apartment or being withdrawn by pipes or tubes.

The pieces 0 increasing in length from the open end to the rear insurean equal distribution of the heated air upon the portion of thefabric-or yarn above the openings, because, as first piece 0 extendsonly a little way down inside, but a small portion of the inrushing hotair will be deflected outward through the first opening I), and agraduation of the amount of the escaping heated air is continued to theend of the chamber by the gradual increase in length of the pieces 0.Thus the drying action is equal and uniform throughout the length. ofthe box, and every portion of the article being dried thereon is actedon equally and dried with uniformity, and so it comes out in perfectcondition, a result not at all certain where no means are provided forequalizing the action of the dryin agentethat is, the heated air allalong the drying-box.

What I claim is 1. A chamber or pipe closed at one end and open at theother, having in one of its sides narrow transverse openings, from theedges of which openings, nearer the closed end of the chamber, extenddownward within. the chamber curved pieces or Wings, which graduallyincrease in length as they approach said closed end, substantially asdescribed.

2. The rectangular box a, adapted to be connected at one end with ahot-blast pipe and closed at the other end, and having in one of itsbroader sides transverse openings Z) at suitable intervals from end toend, and within the chamber the curved pieces 0, placed, re- 20spectively, at the rear of said openings 1), and increasing in lengthfrom front to rear, substantially as set forth.

In testimony that I claim the foregoing I have. hereunto set my handthis 14th day of 2 5
